Specifications, Pricing and Availability

Silicon Power doesn't give us a whole lot of info on the spec sheet, but the official product page is loaded with information. The Slim S70 ships in four capacity sizes - 60GB, 120GB, 240GB and a large 480GB. The S70 is Silicon Power's 7mm z-height model as opposed to the V-Series products that are 9.5mm tall. We're looking at the fastest capacity size today, 240GB.

With the motto, re-write your SSD experience, the Silicon Power S70 pairs LSI SandForce's SF-2281 controller with Intel 25nm synchronous flash to produce a high-speed user experience. The claimed sequential read speed is 557MB/s and the sequential write speed is 507MB/s. The claimed write speed is lower than many of the other similarly configured drives on the market, but in our testing we found Silicon Power sandbagged a bit. We also found the claimed 4K random write IOPS performance to be low as well. We achieved much higher results.

Silicon Power's accessory package is thin. You get the drive, a paper manual and a set of screws for installing your drive. The screws are a little odd since you don't get a desktop adapter bracket. The warranty is stretched to three years, but that's average these days.

At first we had a difficult time finding the Slim S70 for sale. Google Shopping came up empty, but Amazon saved the day with the 240GB listed at $199 and the 120GB at $99. The prices aren't exceptional, but they are not bad either.

Let's take a look at everything and see how the drive performance and see what the Slim is all about.
